I haven't spent a lot of money on cameras..I don't have a lot of money to spend on them. I was given an earlier model of the Akaso camera as a gift, and I bought this V50X recently to add to my collection for YouTubing.All I can say about image stabilization is WOW! I can literally run around while holding this camera, and the resulting video is super smooth. 4K video is nearly a must for any YouTube channel these days, and this camera doesn't disappoint in that regard either.Battery life is what you'd expect of one at this size. I haven't timed it, but I've never been left surprised that it died. You do get 2 batteries in the box, so you'll be set to record video for a good amount of time.The only real downside I can say anything about is the audio quality. The built in microphone isn't terrible, but it isn't really good either. I may grab the external mic at some point, but I can only use that if I'm carrying the camera around - I use it on a small tripod quite often to record something I'm doing rather than capturing my own viewpoint/perspective.The bottom line is that for the price, I'd definitely recommend this camera due to its great video quality.
